Should you upgrade your boiler or choose a renewable heating system?
If your existing boiler is unreliable, your radiators are struggling to heat your rooms or your energy bills are increasing, it may be time to consider an upgrade. Depending on your property, budget and current heating setup, replacing your boiler or improving your existing central heating system could be the right option.
However, if you are planning a major renovation, building a new home or looking to reduce your reliance on fossil fuels, renewable heating is also worth considering.
Air source heat pumps are an increasingly popular option for homeowners in Cornwall. They work by extracting heat from the outside air and transferring it into your home to provide heating and, where configured, hot water. They can operate in cold weather and work particularly well in properties with suitable insulation and correctly designed heating systems.
The best solution depends on factors such as your property’s heat demand, available space, existing radiators and budget. A professional assessment can help establish which system is most appropriate.

Is underfloor heating a good choice for your home?
Underfloor heating provides warmth across the floor, helping to distribute heat evenly throughout a room. Unlike conventional radiators, which concentrate heat around individual points, it can create a comfortable, consistent temperature throughout the space.
It generally operates at lower water temperatures than traditional radiator systems, making it an excellent partner for an air source heat pump. This combination can help improve overall heating efficiency when the system is properly designed and installed.
Underfloor heating is particularly worth considering for new builds, extensions, bathroom renovations and larger refurbishment projects, where the floor construction can accommodate the installation.

At Piran Plumbing, we are registered installers with Nu-Heat for air source heat pumps and underfloor heating. Nu-Heat is MCS accredited, helping homeowners access specialist expertise when considering renewable heating.
Eligible households may also be able to access financial support through schemes such as the Boiler Upgrade Scheme. Funding rules and eligibility requirements can change, so it is important to check the latest criteria before making a decision.

How can you make your heating system more efficient?
You do not always need a completely new heating system to improve comfort and manage energy costs. A few practical changes and regular maintenance can make a difference.
Start by checking that your radiators heat evenly. If a radiator is cold at the top, it may need bleeding. If several radiators are performing poorly, the system may need further investigation.
Other useful steps include:
– Using thermostatic radiator valves to control temperatures in individual rooms.
– Avoiding unnecessarily high thermostat settings.
– Keeping up with boiler servicing and heating system maintenance.
– Investigating persistent cold spots, unusual noises or slow-heating radiators.
– Considering power flushing if sludge and debris are affecting circulation.
Moving radiators, replacing faulty valves or upgrading older components may also improve how effectively heat reaches the rooms you use most.
